Some observations: Four of the top 20 are trucks. Surprised? Even with the specter of fuel prices rising at some undefined future point, many people need pickups. (Need is different from want ... as evidenced by the lack of full- and mid-size SUVs on the list.) Compact SUVs, however, did well (the RAV4 is still a compact in my opinion...but it's not worth fighting about). The balance of the list is what you'd expect with a couple notables; Honda's Odyssey deserves respect for making the list, but I can't fully understand the #8 ranking of the Chevrolet Impala. How can this old Chevy outsell the vastly superior and better driving Chevrolet Malibu? Thoughts?
